CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No.16/424,629, filed May 29, 2019, which claims priority to U.S.Provisional No. 62/677,731, filed May 30, 2018, which disclosures areherein incorporated by reference in their entirety.

BACKGROUND

In the biopharmaceutical industry, both traditional stainless steel andsingle use technology systems have been used for bioproduction (i.e.,Growing cells within a fluid medium and later harvesting a product.) aswell as for simple mixing systems used to combine powered cell culturemedia and a fluid to create a cell culture medium capable for providingnutrients for living cells. These systems have processes that need to becontrolled such as inflation of flexible liners that may requirepressure monitoring systems using in conjunction with mass flowcontrollers to provide air flow, mixing which may require an agitatorwithin the flexible liner being driven by a motor, or pH control whichmay require a pH sensor and the ability to add an acid or base solutionfrom a reservoir either manually or with a pump.

Historically, an operator may have had to inflate a flexible liner to acertain volume and then check environmental conditions and manually makechanges. For example, an operator may have had to add a certain amountof powered medium to a vessel or flexible liner and then turn on amixing device. Sometime later, the biologist would then check the pH andadd an acid or a base using a pipette, mix the system and wait to checkthe pH again.

As the biopharmaceutical industry started to mature, more complexcontrol systems became available that automated some of the manual stepsbiologists by adding layered and continuous feedback loops. For example,a control system would have been able to measure a pH continuously andadd acid or base at a very slow rate to achieve the desired final pH.

This form of control solved some issues for the biopharmaceuticalindustry, but also introduced other problems. For example, thecontrollers that are currently available on the market are difficult tocustomize so generally when a facility is being set up an automationengineer is required to program these controllers using a programming orscripting language. The level of expertise involved makes it difficultand sometimes impossible for the end-user to make changes to an existingcontrol system without assistance.

Another problem that was created by currently available control systemsis that the multilayered, continuous feedback systems do not mimic theprevious legacy validated standard operating procedures used byoperators before this kind of automation was available. For example, ifa validated legacy process specifies dose X and to wait Y minutes thenany automation should be able to follow the legacy process withoutdeviation.

An additional problem is that the currently available control systemsprovide the user with large amounts of unnecessary data even when thegoal is to control a simple procedure. For example, a control system maydisplay dozens of functions whether active or not even when an enduser's only goal is to inflate a flexible liner and add a liquid.

BRIEF SUMMARY

What is needed is a highly customizable system that is user friendly.Such a system will allow a user to simply create recipes and processworkflows through a simple user interface and control the appearance ofthe user interface without the need to contact an automation engineerwith expertise in programming and scripting. The ability to controlvarious types of workflows ranging from the very complex to the verysimple without the controller supplying unnecessary information ishighly desirable. The control system disclosed in the writtendescription and claims of this application will allow a user toimplement recipes used by biologists that do not have to be based onmultilayered and continuous feedback systems. Further, the disclosedcontrol system will allow users to create their own alarm systems todetect failures instead of providing a set of hardcoded alarms that maylead to system wide failures that are unforeseen by the end user.

In various embodiments, an example of a feedback loop may includemeasuring the conductivity within interior of the flexible compartment428 using the conductivity sensor 532. The conductivity sensor 532 maythen relay information by wireless or wired communication to theconductivity transmitter and detection circuit 558 which may relate tothe dissolved oxygen content within the interior of the flexiblecompartment 428. The information may then be relayed to the centralprocessing unit 556 by wireless or wired communication. The centralprocessing unit 556 may access the memory 552 which can identify thetype of information being received and from which device. The memory mayalso include instructions for actions to be taken depending on whatinformation is being received. For example, if the gas content is toolow the memory may include instructions to add gas into the interior ofthe flexible compartment 428. The central processing unit 556 may thenactivate the sparger valve circuit 548 to open a valve or mass flowcontroller 516, 418 which can then release gas from a gas supply 526which can enter the interior of the flexible compartment 428 through thesparger 518, 420. Once the conductivity sensor 532 registers a valuewithin a defined range the sparger 420 can be deactivated or the gassupply 526 can be adjusted accordingly.

In various embodiments, an example of a feedback loop may includemeasuring the weight of the cell culture media mixing system 500, 400,100 using a load cell 528. The load cell 528 may then relay informationto the load cell transmitter and detection circuit 546 using wireless orwired communication. The load cell transmitter and detection circuit 546may then relay the information to the central processing unit 556. Thecentral processing unit 556 may access the memory 552 which can identifythe type of information being received and from which device. The memory552 may also include instructions for actions to be taken depending onwhat information is being received. For example, if the weight of thesystem is too low during a fluid filling phase of a recipe the centralprocessing unit 556 may activate pump drive circuit 540 which canactuate the pump 514, 416 which can then draw fluid from the reservoir520, 424 thereby adding fluid to the interior of the flexiblecompartment 428. Once the load cell 528 registers the proper weight thepump drive circuit 540 can actuate the pump 514, 416 to close and stopthe process.

In various embodiments, an example of a feedback loop may includemeasuring the pressure within the interior of the flexible compartment428. Such a reading may be particularly important during installation ofthe flexible compartment 510, 434 within the rigid housing 110. Thepressure sensor 530 may detect the pressure within the interior of theflexible compartment 428 and then relay the information to the pressuretransmitter and detection circuit 544 using wired or wirelesscommunication. The pressure transmitter and detection circuit 544 maythen relay the information to the central processing unit 556. Thecentral processing unit 556 may access the memory 552 which can identifythe type of information being received and from which device. The memory552 may also include instructions for actions to be taken depending onwhat information is being received. For example, if the pressure isbelow a certain amount the pump 514, 416 may be activated through thepump drive circuit 540 which may then release air from a reservoir 520,424 filled with compressed air. The pressure sensor 530 may continue totransmit up-to-date readings which will ultimately cause the pump 514,416 to close once the flexible compartment 510 has reached a desiredpressure.

In various embodiments, an example of a feedback loop may includemeasuring the pH within the interior of the flexible compartment 428.Such a reading may be important which trying to optimize cell growth orfor acquiring a pH for a fluid 506,408 to be used in another process.The pH sensor 534 may detect the pH within the interior of the flexiblecompartment 428 and then relay the information wo the pH transmitter anddetection circuit 542 using wired or wireless communication. The pHtransmitter and detection circuit 542 may then relay the information tothe central processing unit 556. The central processing unit 556 mayaccess the memory 552 which can identify the type of information beingreceived and from which device. The memory 552 may also includeinstructions for actions to be taken depending on what information isbeing received. For example, if the pH is too high based on a valuestored in memory 552 the pump 514, 416 may be activated to deliver abase from the reservoir 520, 424 or, alternatively, if the pH is too lowthe pump 514, 416 may be activated to deliver an acid from the reservoir520, 424. Any of the values and information for any of the variousprocesses described contained within the memory 552 may be entered by auser or may be part of a recipe.

In various embodiments, an example of a feedback loop may includemeasure the temperature within interior of the flexible compartment 428.Such a reading may be important for a variety of reasons.

A device 522 or thermal sensing device 522 may be atemperature reading apparatus which can convey the temperature withininterior of the flexible compartment 428 to the device control circuit550 using wired or wireless communication. The device control circuit550 can then relay the information to the central processing unit 556.The central processing unit 556 may access the memory 552 which canidentify the type of information being received and from which device.The memory 552 may also include instructions for actions to be takendepending on what information is being received. For example, if a stepin a recipe calls for the temperature to read as X and the currentlytemperature is reading as Y based on the input from the device 522 thecentral processing unit 556 may activate the thermal control element(heating/cooling) 536 which can then relay instructions to the thermalcontrol element (heating/cooling) 536 to increase or decrease thetemperature within the interior of the flexible compartment 428.

In various embodiments, an example of a feedback loop may include usingany of the previously described sensors in conjunction with the mixingelement 508, 404. More specifically, as fluid 506, 406 is added tointerior of the flexible compartment 428 the central processing unit 556may send instructions to the agitator drive circuit 538 to alter thestate of the motor 504, 402, 106 to turn on or increase a rotationalrate which can turn the driveshaft 430 which is rotationally connectedto the mixing element 508, 404. In another embodiment, after anenvironmental condition is met or after a period of time the centralprocessing unit 556 may send instructions to the agitator drive circuit538 to decrease a rate of rotation or turn off the motor 504, 404, 106.

In various embodiments, when a device 522 begins communication with theintegrated control unit 102 (i.e., a device gets plugged into thesystem) central processing unit 556 may detect a signal which can thenbe compared with a library of signals stored on the memory 552 in orderto determine what kind of device is being accessed (i.e., a sensor,pump, etc.) The memory may further include instructions for autocalibration of the device 522. For example, if the device is a pH sensor534 it may be calibrated in order to take accurate pH measurements fromwithin the flexible compartment 428. In some embodiments, after thedevice 522 is recognized a bioprocess module 604 may be activated andautomatically arranged within a bioproduction workspace 602 based on aset of processes or tasks selected by the user or predetermined by thesystem.

In various embodiments, the valve or mass flow controller 516 may bebuilt into the integrated control unit 102. The integrated control unit102 may include one or more gas inlets connected to the valve or massflow controller 516 and a flow path may lead from the valve or mass flowcontroller 516 to an outlet from the integrated control unit 102. Theoutlet on the integrated control unit 102 may then lead to the flexiblecompartment 510. The sparger valve circuit 548 may include instructionsthat determine the rate of gas flow coming from the mass flow controllerbased on the reading from the pressure sensor 530.

In various embodiments, the integrated control unit 102 may includepinch valves for reducing or stopping flow of fluids being cycledthrough the unit 102. In some embodiments, the integrated control unit102 may include one or more pneumatic cylinders and pinch valves forfilling the flexible compartment 510. In some embodiments, theintegrated control unit 102 may include one or more proportional valvesto inflate the flexible compartment 510.

In various embodiments, data can be collected from the various circuitswithin the integrated control unit 102 and sent to a desktop computerfor further processing. In some embodiments, data can be transferred toa USB drive from the integrated control unit for ease of transfer.
